The show with the dosed apple juice took place on the 6th and there's a lengthy conversation on the show you're thinking of in the book Jerry on Jerry.

Well, have I got a show for you! The centerpiece is definitely the run of Lovelight> The Things I Used To Do> Who's Lovin' You Tonight.Don't miss the first set run of He Was a Friend of Mine> China Cat> New Potato Caboose which is also excellent.

if 5/2/70 is the Gold Standard, this one is a nary a shade behind...an exemplary excursion of the group mind that is The Grateful Dead!

I looked up this set after reading phils "Searching Fot the Sound" it was one of the best descriptions of an LSD exsprence ive ever read.
" I looked over at Jerry and saw a bridge of light like a rainbow of a thousand colors streaming between us; and flowing back and forth across that bridge: three-dimensional musical notes - some swirling like the planet jupiter roatating at 100 times normal speed, some like fuzzy little tennis balls with dozens of legs and feet(each foot wearing a different sock!), some striped like zebras, some like pool balls, some even rectangular or hexagonal, all brilliantly colored and evolving as they flowed, not only the notes that were being played, but all the possible notes that could have been played. That moment may well have been the peak of psychedelic music for me - the combination of absolute inevitability and estatic freedom has never been equaled."
Phil Lesh 1969

This is the show that Phil claims to have been dosed at the milligram (not microgram) level. Read about it in Searching for the Sound. He did not recognize his bass at first. Phil claims this was the peak of psychedelic music creation for him.

The show is pretty good and the sound is great for '69.

High quality stereo audio, excellent mix.

5 star recording/mix, 5 star show. Highly Recommended.

It's the Fillmore West.

Eat, drink, be merry and listen to the GRATEFUL DEAD.

Thanks for the love.
